Regenerative bricks are widely used in industry, construction and other fields because of their heat resistance and pressure resistance. There are three main types of bricks: heat storage bricks
1. Burning regenerative bricks:
The fired regenerative brick is made of fine ingredients of magnesia and chrome ore, and the content of Cr2O3 is adjusted according to different needs. The product has good thermal stability and high temperature performance, and is widely used in cement kilns, non-ferrous metallurgical furnaces, etc.
2. Directly combine heat storage bricks:
heat storage brick
Directly combined heat storage bricks use chrome ore with low impurity content and high-purity magnesia as raw materials, which are formed by high pressure and fired at high temperature above 1 700 ℃. Good high temperature performance and strong slag corrosion resistance. Resistant to cement clinker erosion. Widely used in non-ferrous metallurgical furnaces and cement rotary kilns.
3. Semi-recombined heat storage bricks and recombined heat storage bricks
Semi-recombined heat storage bricks and recombined heat storage bricks use part or all of fused sand (electrically fused synthetic sand) as raw materials, fine ingredients, high pressure molding, ultra-high temperature calcination, good particle bonding, high product strength, and stable volume It has good performance and is widely used in RH, VOD, AOD and other out-of-furnace refining devices, non-ferrous metallurgical furnaces, etc.
High temperature sintered heat storage brick series
Iron heat storage bricks, magnesia ferrosilicon heat storage bricks, magnesia heat storage bricks, 92,95 standard-shaped heat storage bricks
1. Iron heat storage bricks
Main ingredient: iron, sintered at 800 degrees.
Performance: fast heat storage, fast heat release.
Advantages: Although the price is cheap, its own weight is relatively heavy.
2. Magnesium ferrosilicon heat storage brick
Main ingredients: magnesium, silicon, iron, sintered at 1350 degrees.
Performance: The rate of heat storage and heat release is moderate, and the strength of the brick is better than that of the iron brick.
Advantages: The price is slightly higher than that of iron bricks, but the cost performance is much better
3. Magnesia brick
Main ingredient: magnesium, sintered at 1500 degrees.
Performance: stable heat storage and heat release performance, strong heat storage capacity, 10KV high pressure resistance, 1500° high temperature resistance, and long heat release time.
Advantages: Large-scale thermal storage equipment is a tall and high-quality product, with long service life and good strength, creating a brand-name product!
